stk3310 and stk3311 are typically connected to power supplies for the
chip (vdd) and the infrared LED (leda). Add properties so we can power
these up / down appropriately.

Found iommufd_viommu_p2-v5 misses some patches,
Simply tested ok with iommufd_viommu_p2-v5-with-rmr, (with some hacks)

Currently, all Qualcomm remoteproc client drivers have data structures
with many common fields. Clean these data structures to categorize the
common fields and create macros to fill rproc-driver-data instances.

This allows the driver to properly handle powering this device, and
disable power during suspend.

In the Pine64 PinePhone, the stk3310 chip is powered by a regulator that is
disabled at system boot and can be shut off during suspend. To ensure that
the chip properly initializes, both after boot and suspend, we need to
manage this regulator.
Additionally if the chip is shut off in suspend, we n
The testing is done by ensuring that the fragment allocated
from a frag_frag_cache instance is pushed into a ptr_ring
instance in a kthread binded to a specified cpu, and a kthread
binded to a specified cpu will pop the fragment from the
ptr_ring and free the fragment.

Inspired by [1], move the page fragment allocator from page_alloc
into its own c file and header file, as we are about to make more
change for it to replace another page_frag implementation in
sock.c
As this patchset is going to replace 'struct page_frag' with
'struct page_frag_cache' in sched.h,
Use appropriate frag_page API instead of caller accessing
'page_frag_cache' directly.

If the chip isn't powered, this call is likely to return an error.
Without a log here the driver will silently fail to probe. Common errors
are ENXIO (when the chip isn't powered) and ETIMEDOUT (when the i2c bus
isn't powered).

Changes in v2:
- us
Using devm callbacks helps to make the ordering of probe / remove
operations easier to reason about and removes some duplicate code
between the probe error path and driver remove.
